I think it depends on the price range. I sell my BatteryBar applications for anywhere from $1 to $10 (time-limited or unlimited). In that price range, I get far lower fees using PayPal's micropayments (5c + 5%) pricing than the default ($0.30 + 3%). That higher pricing is also common for credit cards. So I would say that if you are accepting average payments below $10, get micropayments processing from PayPal or Amazon. If you're charging more than that (as you stated), why no offer both? Have a credit card entry form and off to the side have a PayPal button. I know I prefer PayPal since it's easy and I know how much I have available to spend.
